Recommended Accessories



The unique configuration of these Operators allows the gate arm to rotate from underneath the Operator, enabling the arm to attach to the bottom rail of the gate, were it is virtually unseen from outside the gate. The fully enclosed Operators prevent water from contaminating the output shaft, bearings, and electronics. Additionally, the frame is built from G90 galvanized steel to prevent rusting. These Operators can be installed directly on a concrete pad, or post-mounted to meet any installation requirements.

With safety in mind, these Operators contain an electronic and mechanical inherent reverse system for two methods of obstruction detection. The automatic electronic limits, along with the microprocessor-based electronic control board provide advanced features not typically found in Operators in this class.
